The rollerconveyor-illustrated in Fig. 1 `as an embodiment of 'the invention includes the-section Vl!) comprisingseveral rollers carried in sideframe plates l2, said plates being connected by cross members I-4, -I'4 and supported'onlegs lr6, I-6,said legs .beingconnected in pairs'by tie members l1. This section may be `considered as the terminal portion of a 'longer gravity conveyor extending from a factoryproduction line or serving "as -a part thereof, or installed in a shipping room for delivering the fnished product. The 'present invention is primarily concerned with additional :short sections which are pivotally connected to constitutean'articulated portion of the conveyor :adapted to l'be variously larranged. Fig. 1 vsuggests -tha't ftheadditional sections may follow ra "contourcurving first to the right andthen to the left, so Vas'to terminate at a point A, laterally'offset from -the center line of the section fl-ll. In dotted outline, -Fig. 1 shows an arrangement of vthe same articulated sections in -direct line with 'the section I-D so 'as to terminate lat B, while 'a ythird Vlarrangement fis shown in :dotted outline, `terminating at Ypoint C, oiset 'to the left of the rcenter line =of the 'section I'0. It may be -asvsumed, :for'exampla that the points A, B, and-C represent separate loading 'stations or platforms to whichthe :product traveling fromthe conveyor "section =I0 is to be delivered, fto be loaded onto trucksor cars, `andfthat 'when the truck at A has lbeen filled, 'the articulated conveyor fcan 'be shiftedtoideliverto the platformB and eventually ito the platiorm 'C`, as required. From a confsideration -of the following description of ytl-Ie structure itlwill be-evidentthat various other arfrangements'could be made; `for example, the'c'on- -veyor might terminate'along 'a direction at right 'angles 'to 'the center lline of the section lll from which loads are passed along to the articulated sections of the conveyor.
To provide for these various possibilities, 'the articulated portion of the conveyor consists of a number "of short sections of the :type designatedby theletter `D in 'Figs 2 Vand 3, fand inter# posed coupling sections, each designated Abiyith'e letter E in said views. Each of `the type-1D sec- :tions fco'nsists of a pair 4of angularv bars vwhich serve vas cross members 1'8, connected Vat their endsfa'syby welding, to side plates `2|] 'fwhiehserve to support rods or axles F22 on which A'conveyor rollers 24 are rotatably mounted. leg mem' ber 26 is Welded or otherwise secured at its upper end to each of the side plates 20, and at its lower end is provided with an adjustable foot 28. Cross ties 21 rigidly connect the legs 26. The rods or axles 22 may be removably secured in the plates 20 by :any convenient means. As shown in Fig. 2, the type D sections alternate With the type E sections, and the legs 26 of the type D sections are maintained in Vertical position by means of horizontal bracing members 30, each comprising a, larger tube 32 and a smaller tube 34 telescoped within it, said tubes being rigidly attached to terminal sleeves 36 and 38, respectively, which fit snugly but rotatably over the legs 26. Each leg 26 is provided with a collar 40 or other means forming a shoulder on which the sleeves 36 and 3B rest, as shown in Fig. 3.
VThe legs of the rst movable supporting section D may be connected to the forward legs I -6 of the stationary conveyor section I by horizontal bracing 30 similar to that just described 4as Shown in Fig. l3. Each of the type D sections includes a pair of upwardly open coupling sockets 42 secured respectively in rigid relation to the cross bars I8 atthe middle of their length, so that one of said vcoupling sock-ets is presented at the front of secthe front and rear of the section. vCylindrical coupling pivots 54, in the form of short sections of tubing, are welded or otherwise rigidly secured tothe projecting end portions of the T-bar 52 so` as to depend therefrom in spaced relation to the cross members 48. This arrangement permits the coupling pivots 54 to engage vin the sockets 42 so that a type E section connects two type D sections, as shown in Fig. 7, and said type D sections support the coupling section E between them, with the end portions of its T-bar 52 resting upon the upper ends of the sockets 42, and with the legs 26 of the type D sections supportingthe entire assembly. To stabilize the coupling section E, it may be provided with rigidly attached lbars 56 disposed intermediate the bar 52 iand the side plates 56, and projecting forwardly and rearwardly of the section E far enough so that their end portions rest upon the cross members I8 of the adjacent type D sections. Thus the rollers 24 of each section are maintained in substantially horizontal alignment with the rollers 24 of the next section. However, by reason of the pivotal couplings between the sections, they may be arranged with the rollers of each section disposed iniangular relation to the rollers of the next section, as shown in full lines in Figli.:
When the rollers 24 are thus angularly arranged, the ties between the legs 2-6 must'accommodat'ethe'mselves accordingly, and this is permitted by the telescopic relation of the parts 32 and 34. If desired, each of the outer tubes 32 may be vprovided with a set screw, as indicated at `53, or with any other convenient clamping expedient, for holding the ties at adjusted position so as to maintain the desired contour of the runway formed by the rollers 24. f..
When the runway includes curved portions, as shown in Fig. l, leading to the delivery points A and C, it is desirable that the rollers 24 be made in short sections so as to accommodate their speed more accurately to that of the two sides of the box or other load as it travels over them; accordingly, Fig. 2 shows these rollers extending only about half way across the conveyor. The axle rods 22 of the type E sections are supported at the middle by the upstanding Webs of the T-bars 52, and the T-bars 52aL similarly support the axles 22 in the type D sections; upwardly open notches 63 are formed in the Webs of the T-bars to receive the axle rods22. The webs of the T-bars 52 are shown with inclined end portions at '60 'and 62 which serve to reinforce the flanges of said bars which project beyond the cross-members 48 and transmit loads from the rollers 24 of the type E coupling sections onto the upper ends of the sockets 42l and thence Vthrough* the cross-members I 8 of the type D sections to the side plates 20 and legs 26 thereof.
Preferably, the side plates 20 sand 5I) of the legsupported sections and coupling sections, respectively, extendfsomewhat above the upper surfaces "of the rollers 2'4 so as to act as guard flanges to prevent loads or packages from rollingoff the conveyor, and, as shown, the initialrsection Il) has side plates I2 of the same height .as the side plates 20 and 50, and serving a similar purpose. In a conveyor section which is always straight, there is no occasion for employing short length rollers, and the rollers 64 of the section IU are therefore unitary from end to end. c
For most purposes it will be desirable that the load-carrying surface formed lby the rollers 24 and 64 be slightly'inclined downwardly toward the delivery points'A, B or C, and if the supporting floor is practically level, the inclination of the conveyor can be effected by adjusting the foot-pieces 28 of the several legs 26 lat different positions. As shown in Fig. 4, each foot-piece includes a threaded stern or shank 29 on which a nut 3| is adjustable to serve vas a shoulder for engagement by the lower end of the tubular leg 26. If the 'floor should have irregularities or depressions, as suggested at y66 in Fig. 3, the ad justable foot-piece 28, which, in this'particular instance, is shown associated with the leg I6, may be extended into the depression to keep the adjacent portion 'of the conveyor at the desired level. To permit the slight tilting of any of the short sections with respect to adjacent sections, the tubular coupling pivots v54 have outside diameters which are slightly smaller than the inside diameters of the sockets 42, thus permitting slight axial misalignment of these parts in coupled relation, When necessary.
Preferably, ias indicated in the drawings, most of the parts of this rstructure 4may be joined by means of simple"' weldsl For example,- the side plates 20 and 5 0 can be welded directly tof the ends of the angular cross members I8 and 48.'. The coupling pivots and sockets, as well as the legs I6 and 26, may be'lengths of standard tubing,
the sockets 42 being each welded at one side to the adjacent cross member I 4il 4and the pivot members 54, having theirl upperV ends welded to the under surfaces of the tie 'p'late`s52 l' While there is shown and described herein certain specific structure embodying 'the invention and illustrative" thereof; it maybe understood that the yinventionv is notflimited thereto or thereby, but includes all modiiications and alternative forms which may occur' to those skilled in the fart, and which come within the scope of the yappended claims.
